SPECIFICATION forming part of Letters Patent No. 233,067, dated October 12, 1880.

Application filcdApril 14, 1880. (No model.)

1' all whom it may concern Be it known that I, JOHN G. BUZZELL, of the city of Lynn, in the county of Essex and State of Massachusetts, have invented a new 5 and useful Improvement in Baffin g Machinery for Finishing the Bottoms of Boots and Shoes, which I will describe as follows, reference bein g had to the accompanying drawings, which form part of this specification, like letters indicating like parts in the different figures thereof.

Figure l of the drawings represents a side elevation of my device. Fig. 2 is a plan view cut on the line a: or, shown in Fig. 3; and Fig.

3 is a vertical longitudinal section.

shows a complete plan view, with the exception of the jacket I).

My invention consists in attaching a cam to a disk by means of a shaft, said shaft to enter the cam eccentrically thereof, but to enter the cushion-bed in the center of said bed'and perpendicular to the plane thereof, said cam to be connected with the belt-pulley by means of a spindle inserted in the center of the end of the cam. Then emery-paper or other abrasive material is placed upon the surface of the cushion. Then,when the spindle revolves, carrying the cam with it, the cushion will take the motion of the ordinary eccentric-strap, which is the motion adopted in fiuishin g the bottoms of boots and shoes by hand.

I will describe the construction of my device as follows:

The cam A is made inthe shape shown in Figs. 1 and 3, the spindle J being inserted in an opening in the center of the end of said cam, and connecting the cam with the pulley K, as shown in Fig. 1, and thus connecting the cam with the source of power.

A represents a shaft, (shown in Figs. 2 and 3,) said shaft to be inserted in the center of the disk B, and perpendicular to the plane thereof, the opposite end of said shaft to be inserted in the hollowed end of the cam A 4 5 from the center thereof, thus making said cam an eccentric. When the camA is placed in position the hollowed end thereof (shown by the dotted lines in Fig. 2) fits over the platen, which plate is fastened to the disk by means of the screws 2, all of which is illustrated in Fig. 2'

Fig. 3. By this construction the cam A is held in place when revolving. V

When the cam A is in position the pin or key a is driven through an opening in the cam, and in its passage passes through the slot a in the shaft A, and thus the cam A is keyed fast to the shaft A, all of which is illustrated in Fig. 2. One end of the key a appears in Fig. 1.

The weights a,inserted in the cam, and fully shown in Fig. 2, are for a counter-balance.

The disk Bis constructed with the lip B, so that oil used in lubricating the eccentric A and shaft A, and which may perchance work out onto the top of the disk, cannot flow over the side thereof and do damage.

G represents felt or other suitable elastic material,which is placed in what may be called the bottom of the disk B,with the flange 0 (shown in Fig. 3) to hold said felt in place. The jacket 1); made of leather or other suita' ble material, is then placed over the lower surface of the felt O and carried over and upon the periphery of the disk 13. Then the clastio strap M is placed around over the jacket, as shown in Figs. 1 and 3, to hold said jacket in its place, and the cushion is completed.

E is a piece of emery-paper, or other suitable abrasive material, placed upon the cushion in the well-known manner, and as shown in Figs. 1 and 3, and by which the work of finishin g (before described) is accomplished.

Gr shows a rod attached to the disk, and the opposite end inserted in a slot in the standard H. The use of this rod is to prevent the disk 8 5 B from making a complete revolution, and said rod secures to the disk or cushion-holder B the desired motion, which is that obtained when the work of finishing is done by hand. This rod G holds the bufling-tool in place, and at the same time is an invaluable assistant in e11- ablin g said buftingtool to perform the function required of it. The disk or holder B and the cushion or buffer device, taken together, may be termed the buffing-tool.

L and 0 represent hearings in which the spindle J revolves.

The operation of my'inveution is as follows The pulley K, (being connected with the source of power by a belt in the usual manner,) re- IOO volving, carries with it the spindle J, and in turn the cam or bufi'er spindle A revolves, and the shaft A being inserted in the end of the cam, so as to make said cam act as an eccentric, as before described, the disk takes the motion of an eecentricstrap, the shaft A being allowed to turn in the disk. The abrasive ID21- terial E of course assumes the same motion as does the disk, which is the same as is adopted when the finishing is done by hand.

It is obvious that the machine may be arranged so that the surface of the abrasive material shall be at any angle to suit the convenience of the operator.

Having described the construction and operation of my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A buffing-machine having its bufling-tool arranged ecccntrically to the axis of its driving-pulley, and provided with a holding device, by means of which the buffing-tool is moved in an eccentric path Without rotation on its axis, substantially as set forth.

2. In a buffing-machine, the combination of the rotary pulley, eccentrically-arranged buffer-spindle, holder, and buffer with the holding device G, substantially as set forth.

3. In combination, the cam A,wit-h counterbalance a, the shaft A, with slot to, the key a, the plate a, the disk 13, With flange (3 and 0 lip B, the jacket D, the elastic material 0, the elastic strap M, the abrasive material E, the

spindle J, the rod G, the bearings L and O, the standard H, with slot, and the pulley K, all constructed and arranged substantially in the manner described and shown, and for the purpose specified.
